The (truncated) error message I get is:
[1]PETSC ERROR: --------------------- Error Message

--------------------------------------------------------
Confused. I am not sure how to deal with this.
Why is the locally_relevant_solution.size () and
()completely_distributed_solution.size () reported to be twice the size
of the distributed matrix? Are the vectors not distributed?
viz. PETSC ERROR: Mat mat,Vec y: local dim 4160 8450 (on two processes).
What are the (global) vector and matrix sizes supposed to be? Which
parts of the matrix and vectors are supposed to be stored locally? What
I read here is that one of the vectors is partitioned differently than
the matrix...
Cheers
